Another peculiarity noticed is thechange of the relative brightness of lunar objectsduring totality, some of the objects appearingabnormally bright, whilst Aristarchus, in thenorth-east quadrant, ordinarily the brightest objecton the moon, can barely be identified. io8 We would draw our readers attention to the firstarticle in this number of Sciexce-Gossip.

The interest in Polar exploration has, duringthe past month, been greatly increased by the safereturn of Dr. Xansen. Although he has notsucceeded in reaching his goal, he brings home amass of valuable scientific observations. Hesucceeded in considerably reducing the distance,which has already been reached, from the NorthPole. Mr. Jackson, of the Jackson-Harmsworth PolarExpedition, \rill make every effort to reduce approach to the Pole.
